Lately I´ve been busy doing lots of non-turbine related stuff, but today I actually got some work done in the workshop! Smiley



I had to make a temporary front fender to keep bits of the ice track from entering the air intake, so I borrowed my Triumph bobber fender and made some new brackets for it. The front bracket looks a bit weak from the picture but it is sturdier than it looks so I think it will do for a 200km/h run. Can´t go any faster with spiked tyres and 150hp.



With the fender paint drying I made new brackets for the brake fluid containers, earlier I used zip ties but that was not exactly practical.



Just when I had finished that my friend who would paint the fairings called and told me that they were ready so I jumped in the car and picked them up. My very crappy pre-paint job shines through but it is a race bike so as long as it looks good at 200mph I am satisfied. Smiley



Cheers!

There is a tad more yellow in the white than the picture suggests, somewhere towards cream white. It´ll hopefully look great against the black frame.  smiley

Today my good friend Olle came by to help me fit the spiked tyres, he is in the middle of fitting a pair of Roots compressors to his Rolls Royce Meteor V12 equipped tractor puller so I am glad that he could find the time to help out.



Olle has learned the hard way that it can and most often will hurt to fit spiked tyres, this is a picture from 2013 years Speed Weekend when he and a couple of equally Plymouth drunk guys tried to replace a blown tyre on his turbo motorcycle in the middle of the night. When they were finished they had lots of holes in them and it was blood all over the place... smiley



It went really well actually, with spiked tyres you need an inner hose (correct name?) to keep the air in and it is very easy to make a hole in it with the tyre irons.



My daughter Agnes decided to help out by dropping the washers for the front fairing down the workshop floor drain. grin



Before we changed the front tyre we fitted new ceramic wheel bearings.



With the wheels in place again I could fit the fairings to check of the clearance to the spikes would be enough, at least 3cm all over so I am satisfied. smiley



The color is towards cream white and I think it suits the black frame nicely, I´ll try to get the wheels and the aluminum tanks painted in the same color this summer.



Enough clearance for both the spikes and the front fender, perfect!



With Olle as camera man I got some shots on the bike with me on it, it will be a bit tighter with the helmet and the leathers on but still plenty of space for legs and arms.



Not easy to get the head down and still see where I am heading... smiley

Excellent work. I really dig the paint. Contrasts the frame nicely.

That tire changing party looks like it was fun.  Here in Oregon it gets cold during the off season when we change out the tires.  The tire is put near the wood stove so it gets nice and warm, then one bead is put on and the tube inserted.  Next, the wheel is put back near the stove to reheat.  Then the last bead is fitted.  Tires, like other things, are easier to mount when hot.

Yeah, nothin' says "fun" like frozen, bloody fingers.  rolleyes

Anders, there must be some weirdness to riding on spiked tires. What's it like?

Anders,
Those tire are "frightening"!!!! Hard to even imagine that the spike will stay in the tire at 150 mph.

A note on mounting tires to avoid pinching the inner tube.
Never ever pull the tire iron over a 90 degree angle to the wheel. Pull it to 90 deg and then push the tire on with your boot. Once you have pulled the tire iron over 90 deg you will catch the inner tube and press it against the wheel and most likely put a hole in it. Also move the tire irons around the wheel in small increments, no big bites. I like to spit on the tire irons to add some lube but a quick dip in some oil works also.

Nice progress, can't wait till you run this beast!

Anders, check your rule book.  Some organizations want contrasting colors on white bikes.

Black tires and frames and roll cages, etc., count on that rule written for both cars and bikes.  The SCTA rules were, I believe, intended for small, streamlined and enclosed vehicles.
